Took me way too long to realise Noah was looking at the sky in the first panel. Somehow, I thought his hair was his beard, his beard was a ponytail, his eyes were a hat/headband, and he has his back to us.

You don’t need the rhyming slang (though I like that interpretation). The situation is precisely the sort of thing Alan Funt would do on Candid Camera – set up some weird or funny situation and film people’s responses. If he’d had access to Noah he would definitely pull this gag on him, probably with a hidden garden hose and some rented zoo animals.
